Tudor, little brother of Rolex, has unveiled a very interesting dive watch this week at Baselworld - the Pelagos. It not only has all the prerequisites of a good dive watch, it also has the world's most advanced clasp.
The clasp has a unique spring-loaded self-adjusting system which has been patented by Tudor. The clasp adjusts to the changes in your wrist's thickness, which is especially crucial as the human body goes deeper underwater. Basically, Tudor's clasp gets contracts as your wrist diameter changes underwater, (where many watches would actually loosen due to increased pressure). The clasp also has three fine position adjustments for even further optimization of the fit.
Furthermore, the satin-finished titanium case is 42 mm in diameter and can go an impressive 1640 feet (500 meters) deep and comes with a gas escape valve. Luminescent "snowflake' Submariner hands and square hour markers. The bezel features a scratch resistant ceramic insert. The movement is an ETA 2824 with a 38-hour power reserve. The Tudor Pelagos is also available on a rubber strap with divers extension.
